# VectorDirection

Computes the direction angle of a vector as an angle in range the from 0 to 360.

### Syntax

void avl::VectorDirection
(
const avl::Vector2D& inVector,
float& outDirection
)


### Parameters

Name Type Default Description
inVector const Vector2D&
outDirection float&

### Description

Note that because of inaccuracies of floating-point arithmetic, some geometric operations (including this one) may lead to unpredictable results for degenerated cases. In this filter such a case occurs when a zero vector is given on input.

### Examples

VectorDirection performed on a vector with parameters: DeltaX = 10, DeltaY = 10.
outDirection returns 45.
